RUBBER HEEL.

Application filed October 12, 1926. Serial No. 141,150.

This invention felates to improvements in lustrating a slight modification in the man- :rubberv heels for boots, shoes and the'like, lner of. securing the rubber heel in place,

and has for one of its objects to provide an Figure is a similar view illustrating a article of this character which shall be further'modiication in the manner of se- 60 5 equipped with an embedded metal anchorcuring the rubber heel in place, and

The heads 13 of Figure 2 is a bottom plan view of the the screws 12 contact with the flanges 8 of parts shown in Figure 1, the bosses 7 .and engage internally screw- Figure 3 is a detail plan view of the metal threaded hollow bossesv 14.

The bosses 14 extend upwardly from the plate 15 and are embedded in the leather heel lift 3.

In Figure 5, the rubber heel 4 is also..

shown secured in place by screws. rlhe .-5 heads 17 of these screws 18 contact with the engage internally screw threaded hollow' bolts 23 which pass downwardly through the heel carrying base 2 and the leather heel lift 3.,

When the metal plate 5 is exposed as the resultof the wearing away of the rubber heel 4, it provides a smooth wear resisting surface that will not scratch or otherwise mar floors and floor coverings. The vertical dimension of the bosses 7 is greaterthan the corresponding dimension of the heads of' the elements securing the rubber heel 4 in place. In view thereof, the heads of the securing elements are located above the metal plate 5. All possibility of any projection .of the heads below the metal plate 5 is thus avoided. The heads of the attaching elements cannot scratch or otherwise'mar iioors 5 `and floor coverings, especially when the plate is ex osed as the result of the wearing away of t e rubber heel 4, and there is no possibility of the attaching elements, es-

pecially the nails 11 from being forced up -Wardly into the boot or shoe.

4It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions'. Furthermore, the said drawing is illustrative of a preferred construction, it being my expectation that various changes and modifications may be made Without departing from the spirit and scope of my invention. What is claimed is A .rubber heel having a metal anchoring and reenforcing plate embedded therein, said plate being vprovided withV upstanding hollow bosses provided at their upper ends with interior annular iianges, the bosses termihating short of the upper side of the heel and portions of said side of the heel extending across and contacting with the upper ends of the bosses and their lianges,\and attaching elements for securing'the heel in place passing through the bosses and. having their heads arrangedcompletely above the lowersurface of the said plate and in contact with the under sides of said flanges, said construction preventin contact of thehea'ds with a ioor shoul the plate become eX- posed, and openings being formed in the rubber heel below and-in alinement with the bosses.

In ltestimony whereof I affix my signature.
